Ruud, the tournament’s No. 6 seed, battled back in the second, holding serve and keeping pace with his opponent’s repeated drop shots until Tsitsipas finally broke him with a shot down the line to take a 5-4 lead.

Tsitsipas finished off the one hour, 14-minute match with an ace, his eighth of the day.

Aryna Sabalenka and Victoria Azarenka, both of Belarus, kicked off the quarterfinals at the women’s tournament in Montreal on Friday, with the No. 1-seed Sabalenka taking a 6-2, 6-4 victory.

Sabalenka, the world No. 3, went down 4-2 in the second set before winning four games in a row, and had seven aces across the one hour, 19-minute match.

No Canadian singles players made it through to the tournament’s quarter-finals. Bianca Adreescu, the defending tournament champion, battled through two hotly contested sets Friday before Jabeur pulled away in the third for a 6-7 (5), 6-4, 6-1 third-round victory.
